This explores how every aspect of the electric ecosystem is helping to deliver a complete site solution for construction applications.
Volvo CE is thoroughly testing every part of how an electric machine is put to work from a system perspective – from charging infrastructure through to energy supply and more. The Electric Worksite (E-Worksite), which launched earlier this year in Gothenburg, Sweden, not only sets the global benchmark for electric jobsites but also tests electric machines’ specific requirements across different tasks within a demanding urban environment. It is a vital next step in the manufacturer’s electrification journey.
E-Worksite is a long-running research project that explores the site requirements for electromobility over the next two years across a variety of different applications. It has now completed the development of a new recreation area within the major city park Färjenäsparken and is currently working on the redesign of the Drottningtorget city square, both in the heart of Gothenburg, the second largest city in Sweden. Here, the customer transformation from diesel machines into more sustainable environmental solutions is guided by a fully holistic exploration of every aspect of site management. The project is funded by the Swedish Energy Agency, with Volvo CE working in close collaboration with Gothenburg City, NCC, Gothenburg Energy, Lindholmen Science Park, Chalmers University of Technology and ABB Electrification Sweden, among many others to conduct a largescale machine demonstration in Gothenburg.
In this first phase, a number of electric machines already available to buy on the market are being put to the test, including the L25 Electric wheel loader and ECR25 Electric excavator, which are carrying out minor construction work, material moving and landscaping. A larger 30-tonne grid-connected excavator will be tasked with more energy-demanding jobs at different construction sites, to start in spring next year.
Project planners are answering questions such as how to ensure best value for money for customers and what are the most energy efficient methods of supplying electricity to power the machines. Beyond the technology itself, business models, infrastructure and support systems, regulatory frameworks and a mindset change are all required on the road to full acceptance. It is a complex puzzle to solve as there will be no one size fits all. The findings will prove important not only for municipalities in deciding how to develop the appropriate legislation, but also for industry partners in bringing technical solutions to market – both in the immediate future and over the next two decades.
Launching the project in an urban application allows for a demonstration of the advantages electric machines bring to city life – low noise, low emissions, and a much more peaceful environment for society in general. Source
